Microservices Architecture for Orthodontic SaaS: How uLab Systems Modernized Its Platform

From Monolithic Constraints to Cloud-Native Agility: A Case Study in Orthodontic SaaS Transformation

One-liner summary:

uLab Systems partnered with Ideas2IT to modernize its orthodontic planning platform, migrating from a legacy desktop architecture to a microservices-based SaaS platform. The transformation improved billing efficiency by 78% and enabled scalable, web-native deployment.

The Problem with the Status Quo

uLab Systems, a leading manufacturer of clear aligners and dental treatment solutions, had grown rapidly, with hundreds of thousands of orthodontic cases processed through its uDesign desktop software. But scale brought friction.

With monolithic infrastructure, manual billing operations, and platform silos between desktop and cloud, the company struggled to release features quickly, onboard new users seamlessly, and support integrations across the clinical and administrative workflow.

They needed a full-stack modernisation to lead with innovation.

Where the Gaps Were

Key issues identified:

Billing and promotion workflows required up to 45 days due to fragmented systems
The platform lacked microservices, limiting scalability and modularity
Manual deployments slowed down release cycles and created CI/CD bottlenecks
No native integrations with Salesforce, Netsuite, OKTA, or key payment platforms
Desktop-bound UX constrained clinical workflows and limited AI extensibility

Without re-architecting the system, uLab risked falling behind as the business scaled.

What We Delivered

Ideas2IT led the replatforming effort, transforming uLab’s desktop solution into a modular, SaaS-native application powered by microservices and DevOps best practices.

Core Implementation Highlights:

Microservices: Re-engineered patient, treatment, and order modules as decoupled Python (Django) services running in containers
Billing Process Automation: Reduced billing cycles from 45 to fewer than 10 days using a scalable rules engine and optimized data pipeline
Enterprise Integrations: Enabled bi-directional sync with Netsuite, Salesforce, QuickBooks, Adyen, Authorize.NET, OKTA, and AWS services
DevOps Modernization: Implemented ECS and EKS containerization, CI/CD pipelines, CloudFormation, and OPA policy-based authorization
‍Web Transformation: Launched uDesign Cloud 1.0 and uSmile AI, bringing desktop capabilities to the browser with real-time, AI-powered stage prediction

Outcomes We Achieved

Area	Outcome
Billing cycle time	Reduced from 45 days to fewer than 10 days
Release velocity	Weekly rollouts enabled via CI/CD
Clinical data workflow	Migrated to AI-assisted, browser-native environment
Partner integrations	Expanded to 6+ platforms including ERP and CRM
Developer productivity	Improved through service isolation and modular code
Scalability	Enabled growth from solo clinics to multi-site setups

uLab now operates as a cloud-native SaaS platform with real-time order management, automated billing, and AI-powered diagnostics accessible securely via the browser.

Key Takeaways

Microservices are an organizational enabler: With each service isolated, teams moved faster and deployed independently
Automation unlocks scale: Replacing manual billing logic with programmable rules turned a bottleneck into a growth enabler
Modernization is as much about integrations as it is about infrastructure: Real-time sync with Netsuite, OKTA, and payment gateways was critical to business continuity
‍User experience can’t lag behind architecture: Transforming desktop workflows into a clean, AI-enhanced web interface was central to platform adoption
